Ventilator for railroad-cars



UNITED STATES PATENT OFFIOE.

RICHARD B. VRIGHT, OF NORFOLK, VIRGINIA.

VENTILATOR FOR RAILROAD-CARS.

Specification of Letters Patent No. 30,5 15, dated October 23, 1860.

To all whom it may concern:

Be it known that I, RICHARD B. WRIGHT, of the city and county of Norfolk and State of Virginia, have invented a new and useful Improvement in Smoke and Dust Deflector and Ventilator' for Railroad-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l, represents a front view of my improved window, as applied to a car and Fig. Q, a cross section of the same.

Similar letters of reference, in each of the several figures indicate corresponding parts.

The nature of my invention consists, first, in hinging a dust and spark deflector between two car windows so that it may be applied to either of the windows according to the direction in which the car travels. It consists, second, in a V shaped frame hinged and provided with a sash in the center of the said V shaped frame, in combination with a wing of wire gauze hinged to the edge of the sash so as to shut against either of the arms of the V shaped frame.

To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

The horizontal V shaped frames C, C, C, O, are connected by means of a vertical sash containing a pane D. This sash extends from the outer apex J, to the inner apex I, of each of these V shaped frames, so as to divide it in two equal portions C, and C. The outer ends of these arms O, C, and C, C', are respectively connected by strips of wire gauze L, L, and a wing of wire gauze H, is hinged to the edge of the sash at I, so that it may shut against either pair of the arms C, C, or C', C.

The whole device is hinged to the outside of a rail-road car between two windows A, B, at J, so that it may be shut against the window B, if the car travels in the direction of the arrow in Fig. l; or against the window A,-see red lines in Fig. Q-if the car travels in the opposite direction.

The object of this device is to deflect the dust, smoke and sparks, and at the same time to create a strong draft from the interior of the car through the windows.

The car moving in the direction indicated by the arrow in Fig. l, and the detlector being in the position shown in black lines in Fig. 2, the air rushing by the car is deflected as it strikes the pane D, which it will be seen stands at an angle to the side of the car. This current of air has of course a tendency to create a vacuum between it and the car side in rear of the deflector and to fill this vacuum the air rushes from the interior of t-he car out through the windows. The interior of the car is constantly supplied with fresh air through the ventilator X, and by this means a constant current of air is kept up through the car and the windows.

To prevent dust, smoke and sparks from entering the car, the wing of wire gauze H. is shut against the arms C, C, of the V shaped frames which rest against the side of the car. The wing H, in combination with the strip L,-or L if the detlector is in the position represented by red lines in Fig. Q-prevents all dust, smoke and sparks from entering the car.

My invention is peculiar in being hung on a center which is between two windows and thus is supported without a frame, and capable of being changed from one window to another, when the direction in which the car moves is changed.

That I claim as my invention and desire to secure by Letters Patent, is

l. Hinging a dust and spark detlector between two car windows so that it may be applied to either of the windows according to the direction in which the car travels, substantially as set forth.

2. A V shaped frame C, C, hinged at J and provided with a sash D, in the center of the said V shaped frame-in combination with a wing of wire gauze H, hinged to the edge of the sash so as to shut against either of the arms C, or C, of the V shaped frame, substantially as and for the purposes set forth.

The above speciiication of my improvement in spark and dust detlectors and ventilators for rail road cars, signed by me this 22d day of September 1860.

R. B. VRIGHT.
